Notes
Install bearings in a clean environment. Check the bearing housing, shaft and bearing components to ensure that it is clean.

The bearings should be left in the original packaging until the moment before installation to prevent pollution.

Size and shape tolerances of all components in contact with the bearing should be checked.

The diameter of cylindrical shaft neck, usually uses a micrometer to measure each of the four points of the three planes. Survey record forms can be obtained here. Filling out the measurement records and archives appropriately helps future tracking.

The bore diameter of the cylindrical bearing box, usually uses inner gauge to measure each of the four points of the three planes. Survey record forms can be obtained here. Filling out the measurement records and archives appropriately helps future tracking.

Install Program
Wipe off the rust inhibitor in bearing bore and the cylindrical surface.
If bearings greased and use in extremely high or low temperatures, or grease and rust inhibitors are not compatible, it need to be carefully cleaned and dried.

Axis is an interference fit
Slightly lubricate the hole of the bearing with mineral oil.
Ensure that the bearing is vertical with axis after installed.
When installing, use appropriate sleeve to force on the inner ring.

The bearing box for the interference fit
Slightly lubricate the outer peripheral surface of the bearing with mineral oil.
Ensure that the bearing is vertical with bearing box after installed.
When installing, use the appropriate sleeve to force on outer ring.
Shaft and bearing box for interference fit
Slightly lubricate the inner-hole of the bearing with mineral oil.
Slightly lubricate the outer peripheral surface of the bearing with mineral oil.
Ensure that the shaft and bearing box are perpendicular to the axis after adapted and installed.
When installing, use the appropriate sleeve to force on the inner and outer rings at the same time.
Push the bearing to the correct location.
Fit with locking devices.
Determine shaft or outer ring can easily turn.
Bearings lubricate using oil, pay attention to use the correct lubricants and dosage.
Bearings lubricate using grease, be coupled with the grease.
If the bearing is to be put into the shaft and the bearing box both, grease may needs to earlier be added.
Under normal circumstances, this bearing should be completely filled grease, except applied to high speed. Fill grease in the remaining space in the bearing box (approximately 30-50%).
SKF grease LGMT 2 can be used for the general working conditions. Considering the actual working conditions to select grease, see SKF condensed grease selection guide.
